Rivian has initiated an extended recall for more than 30,000 R1S and R1T electric vehicles due to issues with their turn signal lamps. This action follows an earlier recall and now encompasses both 2025 and 2026 model years. The manufacturer attributed the problem to its supplier, Myotek, which reportedly failed to isolate components that did not meet Rivian's quality control specifications, resulting in a broader range of vehicles being equipped with the faulty parts. The core issue involves front turn signals that may not light up or flash correctly, thereby failing to comply with federal regulations for vehicle safety. Drivers will receive a dashboard alert if a turn signal malfunctions.

To rectify this, Rivian will conduct inspections and replace any deficient front turn signal lamps in the affected vehicles at no cost to the owners. The company is urging affected customers to schedule appointments at their nearest service centers, where the repair procedure is expected to be completed in under an hour. This marks the tenth recall for the 2025 Rivian R1S and the second for the 2026 R1S, highlighting the ongoing challenges faced by emerging automakers in ensuring consistent quality as production scales. Despite these setbacks, Rivian's ability to manage recalls effectively is crucial, particularly with the rollout of its more budget-friendly R2 SUV, which is vital for the company's long-term financial viability and market success.

Expanded Recall Details for Rivian EVs

Rivian has broadened its recall efforts for its R1S and R1T electric vehicles, now including a total of 31,711 units. This expansion builds upon an initial recall launched last year, incorporating an additional 3,829 vehicles to the list of those potentially affected. The defect pertains to front turn signal lamps that may not function as intended, specifically, they might fail to illuminate or flash. This malfunction poses a significant safety risk, as it means the vehicles may not meet current federal safety requirements. The affected models now include certain vehicles from both the 2025 and 2026 model years, with the majority being R1S SUVs, alongside a substantial number of R1T pickups.

The root cause of this widespread issue has been traced back to the turn signal lamp supplier, Myotek. According to reports filed with the National Highway Traffic Safety Administration (NHTSA), Myotek allegedly did not adequately isolate and prevent the use of non-compliant parts during the manufacturing process. Consequently, a greater number of Rivian vehicles were assembled with these substandard components. This oversight means that drivers might not be able to signal their intentions effectively, increasing the risk of accidents. Rivian has committed to addressing this problem by inspecting and, if necessary, replacing the faulty turn signal lamps. Owners of the affected vehicles are encouraged to contact their nearest service center to arrange for the necessary repairs, which are designed to be quick and efficient.

Addressing Safety Concerns and Company Impact

The latest recall underscores Rivian's commitment to vehicle safety, even as it navigates the complexities of scaling production for its electric vehicle lineup. The inability of turn signals to operate correctly could lead to dangerous situations on the road, making timely and comprehensive rectification paramount. Rivian has put in place a clear plan to resolve the issue, offering free inspections and replacements of the front turn signal lamps at authorized service centers. This proactive approach aims to restore confidence in the brand and ensure the safety of its customers, while also adhering to regulatory standards set by bodies like the NHTSA.

For Rivian, a relatively young company in the competitive EV market, managing such recalls efficiently is critical for its reputation and long-term success. The R1S, in particular, has faced several recalls, with this being its tenth for the 2025 model year and second for the 2026 model. Previous issues included improperly secured seat belt assemblies. As Rivian prepares for the broader market release of its more accessible R2 model, maintaining a strong track record of quality and safety is more important than ever. The successful and swift resolution of these issues will be key to demonstrating the company's reliability and building consumer trust, which is essential for its financial stability and future growth in the evolving electric vehicle industry.

While electric vehicles are celebrated for their environmental benefits and efficiency compared to internal combustion engines, many owners are unaware of a subtle yet significant factor impacting their running costs: charging losses. When an EV is plugged in at home, not all the electricity drawn from the grid makes its way into the car's battery. This discrepancy, known as charging loss, means consumers pay for more energy than their vehicle actually receives. Recent evaluations by Germany's ADAC have shed light on the extent of these losses across various EV models and charging setups, revealing that the choice of charging equipment and method can profoundly influence overall electricity expenditure.

The core issue of energy dissipation during the charging process stems from the conversion of alternating current (AC) from household outlets to direct current (DC) required by EV batteries. This conversion primarily occurs within the vehicle's on-board charger (OBC), which can be a significant source of inefficiency. Additionally, other vehicular systems, such as thermal management components like heaters or coolers, also consume power during charging, further contributing to the overall energy loss. Advancements in technology, particularly the shift from conventional silicon semiconductors to more efficient silicon carbide (SiC) components in some modern EVs, aim to mitigate these losses, albeit at a potentially higher manufacturing cost.

ADAC's comprehensive testing involved five popular electric vehicle models: the Mercedes-Benz CLA, Renault 5, Tesla Model Y, Volvo EX30, and Volkswagen ID.7. They subjected these vehicles to three distinct AC charging scenarios: a low-power 2.3 kW mobile charger, a 4.1 kW simulation for solar charging, and high-powered 11 kW or 22 kW home chargers. The findings underscored a critical principle: higher charging power generally correlates with reduced energy losses. For instance, the Tesla Model Y, which demonstrated the lowest losses among the tested vehicles, still experienced a 12.7% loss with a 2.3 kW mobile charger. This figure dramatically decreased to 6.1% when using an 11 kW home charger, illustrating the efficiency gains associated with more powerful charging solutions.

Conversely, some models exhibited notably higher inefficiencies with lower-powered charging. The Mercedes-Benz CLA, for example, registered a substantial 24.2% energy loss when charged via a 2.3 kW mobile unit. This was attributed to an 8-ampere current limit imposed by Mercedes-Benz on its on-board charger for mobile charging. However, transitioning to an 11 kW wall charger brought its losses down to a more respectable 6.9%. Interestingly, the Renault 5 emerged with the lowest charging losses when connected to an 11 kW dispenser. The Volvo EX30 was unique in its support for 22 kW charging, though the efficiency improvement over an 11 kW charger was minimal, showing 6.7% losses at 22 kW versus 7% at 11 kW. All tests were meticulously conducted with battery charge levels between 10% and 90%, and temperatures maintained between 68°F (20°C) and 86°F (30°C) to ensure consistent and reliable data.

Understanding and addressing charging losses is paramount for electric vehicle owners seeking to optimize their energy consumption and reduce operational expenses. The ADAC's research clearly demonstrates that investing in a higher-powered home charging solution can lead to long-term savings by minimizing wasted electricity. While mobile chargers offer convenience for occasional use, relying on them regularly can significantly inflate electricity bills due to their inherent inefficiencies. By opting for faster, more efficient charging infrastructure, EV users can ensure a greater proportion of the energy they pay for is effectively utilized to power their vehicles, contributing to both economic and environmental sustainability.
